Subject: [PATCH] backport of patches 2.10, 2.11, 2.12, by MvL. . Patch
 #455231: Support ELF properly on OpenBSD. . Patch to bug #472202: Correctly
 recognize NetBSD before 199712. . Move dlfcn.h block out of NetBSD block,
 assuming that NetBSD before   199712 didn't have dlfcn.h, or that it wouldn't
 conflict with the other   stuff defined.
